State of the art NL

• Small wind turbine manufactures
• Excellent production facilities offshore
  constructions (I.e. monopiles)
• Strong RD position
• Strong offshore industry and project development
• A lot of activities (rotor design, mechanical
  engineering, design facilities) in NH

OM Optimisation Long Term OM Cost Estimator

• Quantification of future OM costs and
  uncertainties
• Based on among others condition monitoring data
• changing from corrective maintenance to condition
  based maintenance
• less consequence damage
• better planning of maintenance actions strategy
